    摘要: Eine geschlossene hydraulische Bremsanlage weist zumindest einen Hauptbremszylinder auf, dessen Druck kammer mit einem Reservoir (42) verbindbar ist. Zur En tlüftung der Hydraulikflüssigkeit in der Druckkammer (26, 28) ist ein strömungsabhängiges Ventil (50) zwischen der Druck kammer (26, 28) und dem Reservoir (42) für Hydraulik flüssigkeit angeordnet, Das strömungsabhängige Ventil (50) befindet sich oberhalb der Druckkammer (26), so daß Luftein schlüsse zum strömungsabhängigen Ventil (50) steigen. Sobald der Hauptbremszylinder (10, 12) betätigt ist, wird eine geringe Menge Hydraulikflüssigkeit durch das strömungs abhängige Ventil (50) zum Reservoir (42) gefördert, wonach das Ventil schließt.

    摘要: A vacuum brake booster assembly comprising a brake booster (10) and a hydraulic master-­cylinder (12), the booster comprising an input rod (14), a valve assembly (28) and piston means (26) defining first and second booster chambers, the piston means being connected to an output rod (33) having adjustment means to vary the length thereof ; the piston means having a fist spring (58) to urge it towards a rest position, the master cylinder comprising at least one piston assembly (42) associated with a respective hydraulic pressure chamber for a vehicle braking circuit, the piston assembly having a second spring (50) to urge it into a rest position, the piston assembly and the output rod (33) being adapted to cooperate when the brake booster assembly is in operation; characterised in that the force exerted by the first spring (58) is less than the force exerted by the atmosphere on the piston means when a vacuum is applied to the first and second booster chambers, the combined force of the first (58) and second (50) springs being greater than the said force exerted by the atmosphere.

    摘要: A master cylinder (10) having a sleeve (24) for positioning first (22) and second (30) seal members within a bore (14) of the housing (12). The first (22) and second (30) members each have a primary seal (52), a retainer (58) and secondary seals (54 or 55). The primary seals (52) have a base member (60), a peripheral ring (64) and a flexible section (66). The retainers (56) have a groove (70) for holding the base member (60), radial slots (74, 74') connect to a source of fluid and either a rib (100) or projection (94) for positioning the secondary seals (54 or 55). First (38) and second (40) pistons which engage the first (30) and second (22) seal members, have communication passages (80, 82) through which the radial slots (74, 74') (75, 75') are connected to first (48) and second (42) chamber. In response to an input force, the first (38) and second (40) pistons move into the first (38) and second (42) chambers, respectively, to pressurize fluid therein after interrupting communication through the passages (74, 74') (75, 75'). The fluid pressure acts on the base members (60, 60') to seal the chambers (46, 42) from the source of fluid (23). As the first (38) and second (40) pistons move out of the chambers (46,42), a vacuum may be created therein. The flexible sections (66, 66') allow the peripheral rings (64, 64') to move and permit the vacuum to draw fluid into the chambers (46, 42) to assure that a substantially constant volume of fluid is available to effect a brake application.

    摘要: Ein Hauptbremszylinder für eine hydraulische Bremsan lage ist mit einem Bremskraftverstärker (12) und einer Füllstufe (14) versehen. Eine Füllkammer (42) der Füllstufe (14) ist mit einem Hydraulik-Flüssigkeit-Reservoir (61) über ein Ventil (80) derart verbindbar, daß bei funktionierendem Bremskraftverstärker (12) die Füllkammer (42) in der Anfang sphase der Bremspedalbetätigung geschlossen ist, während bei nicht funktionierendem Bremskraftverstärker (12) die Füllkammer (42) der Füllerstufe (14) mit dem Hydraulik- Flüssigkeit-Reservoir (61) leitend verbunden ist, so daß die Füllstufe unwirksam ist.
